More on translations. This time, we want to know how LONG the vector is. What is the DISTANCE it moved the object.
The vector has an x- and a y- component. There are the same components you use to find slope, but it's not slope. We use them with the Pythagorean Theorem (or the distance formula) to find HOW FAR.
Note that when using GeoGebra, you can use the distance tool and get the measurement directly from the screen.
